Scientists have approached the creation of a drug to treat the two most common causes of vision loss after a successful experiment in mice, US scientists said..

Activation of a specific protein in the eyes prevents damage to the blood vessels, which can lead to blindness. The study deals with macular degeneration and diabetic retinopathy - the two main diseases associated with blood vessel problems.

Most often, these diseases are faced by people in old age. Researchers managed to identify the Robo4 protein, which, as it turned out, played an important role in the formation of strong, working blood vessels.

Scientists have introduced proteins to mice in order to study the effects on age-related macular degeneration and diabetic retinopathy. Scientists have found that damage to blood vessels has been prevented and in some cases there has been a complete regression of the disease.

According to scientists, it is not yet known whether the human body will react to the protein, and what side effects they may encounter, but in any case it is a great discovery and a step forward to creating drugs to treat and prevent the causes of vision loss.
